DuckDuckGo, a privacy-focused search engine, today announced a new feature called Marter Encryption,media reported. It is reported that this feature can automatically upgrade HTTP site requests to HTTPS sites, of course, if the target site supports HTTPS and it is in The List of Upgradeable Sites in DuckDuckGo.
It is understood that most Internet sites are already using HTTPS, but there are still some websites only use HTTP or support HTTP and HTTPS at the same time.
DuckDuckGo’s Smarter Encryption will now be able to automatically upgrade HTTP requests to HTTPS.
Currently, the company behind the search engine has created a list of more than 10 million websites.
Information about the most popular sites that can be upgraded is stored on local devices, but most sites are stored on DuckDuckGo servers.
It is clear that the company has taken privacy issues into account when designing the request, and it notes that all privacy protections and policies apply to Smarter Encryption.
The following occurs when a user tries to access a site that uses HTTP:
1. Check the local list, and if the site is on the list it will be upgraded immediately and complete throughout the process.
2. Sha-1 hash is generated if the site is not in the local list.
3. The first four characters of the hash are sent anonymously to the DuckDuckGo server. Because the request is anonymous, no record is left on the IP address or personal data.
4. The server returns all hashs that match the query.
5. The entire hash checks the list locally to determine if the site can be upgraded to HTTPS.
6. If in the list, the request is upgraded to HTTPS. Otherwise, an HTTP connection is established.
Connections using HTTPS are encrypted, which means that users’ privacy and security are protected when used.
It is reported that the latest version of the DuckDuckGo browser extension and mobile app have provided this new feature.
